Perhaps you should try some spelling variations:
synfire chain » synfire chains, synfue chains
single chains » single chain, single domains, single chip
entire chain » entire brain, entire domain, entire change
singie chain » single chain, side chain, single chip

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((\\"((synfire chain) OR (entire chain))\\") or (\\"singie chain\\"))) or (((\\"single chains\\") or (\\"single channel\\"))))\"".
• Removing quotes may allow a broader search: (((( ((synfire chain) OR (entire chain)) ) or ( singie chain ))) or ((( single chains ) or ( single channel )))).
